Specification of Letters Patent.

Patented Jan. 14, 19 O8.

Application filed April 9. 1907- Sei'ial No. 367-145.

T 0 all whom. it may concern:

Be it known that I W ALTER, I. TISDALE', citizen of the United States, residing at Mo- Neill, in the county of Pearl River and State of Mississippi, have invented certain new and useful Improvements.in Inkstands, of which the following is a specification.

The present invention relates to: certain new and useful improvements in the design of reservoir ink wells", the object being to provide a novel construction whereby the ink is automatically fed as required from a reservoir into a comparatively small dipping well, and is thereby prevented from eing wasted and at the same time effectively shielded against contamination by dust or other foreign matter.

The invention also aims to provide a comparatively simple and inexpensive device of this character which can be readily taken apart and cleaned when found necessary and which will not clog or give any annoyance after a short eriod of use.

For a full escription of the-invention and the merits thereof and also to acquire a knowledge of the details of construction'and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

view of the ink well.

Figure 1 is a vertical sectional view through an ink well constructed in accordance with the present invention. Fig. 2 is a perspective Fig. 3 is a detail sectional view similar to Fig. 1 showing the spring arm as pressed inwardly to close the feed opening from the reservoir.

Corresponding and like parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters. v

The body portion of the ink stand as indicated at 1 may be formed of any suitable material such as glass and is provided at one side with the reservoir 2 and at the oppo- In the resent instance the reservoir portion of the ody 1 extends upwardl somewhat be 0nd the feed portion forme with the cham er 3 and is closed by means of an air tight plug 4. Located at the lower portion of the chamber 3 is the dipping well 5 which communicates with a feed opening 6 leading into the bottom of the reservoir 2. Owing to the fact that the said reservoir is provided with an air tight closure it will be readily apparent that any ink or other liquid within the reservoir will flow through the feed opening '6 into the well 5 until the level of the liquid within the Well reaches the top of the opening 6. At this stage a liquid seal will be formed which prevents air from entering the reservoirthrough the feed opening and the liquid ceases to flow until the level of the liquid within the well 5 shall have again been lowered below theto) of the opening 6. jecting downwardly into the chamber 3 in the feed portion of the bod 1 is a tubular member 7 which is preferab y in the nature 'of a funnel as in the )resent instance and terminates over the-well 5 in such a manner as to lead a en into the latter. The inner or contracte portion of the tubular member 7 is cut off at an angle and is normally closed by a spring arm 8 arranged within the chamber. When a penpointis inserted throu l1 the funnel 7 however the spring arm will Ire forced inwardly and owing to the inclination of the same the pen point will be readily deflected downwardly so as to enter the well 5. This spring arm 8 is also designed to close the feed opening 6 while the reservoir isbeing filled and in order to effectively perform this function a strip of rubber or similar compressible material 9 is referably secured to the rear face thereof. It will thus be apparent that by inserting a pen or any other,

suitable implement through the funnel 7 the spring arm 8 can be forced inwardly and held over the feed opening 6. In the preferred construction of the invention the spring arm 8 is integral withan arm 10 which bears against one of the side walls of the chamber 3 and cooperates with the arm 8 to impart the require resiliency thereto.- Both the funnel 7 and spring 8 are removably mounted within the feed portion of the ink well and can therefore be readily taken out and cleaned when desired.

Having thus described the invention, what is claimed as new is:

1. In an ink well, the combination of a body portion provided with a reservoir and a dipping well, a feed opening being formed in the body portion and establishing communication between the reservoir and the dipping well, and a closure adapted to close either the inlet to the'dipping well or the before mentioned feed opening.

2. In an ink well, the combination of a body portion provided with a reservoir and a dipping well, a feed oipening being formed in the body portion an establishing communi- Procation between the reservoir and the dipping well, and a spring arm adapted to close either the inlet to the dipping well or the before mentioned feed openmg.

3. In a device of the character described, the combination of a body having a reservoir formed therein and comprisin a feed portion provided with a chamber t e lower portion of which is in the nature of a dip ing well, a feed opening communicates between the reservoir and the dipping well, a tubular member extendin downwardly into the chamber of ,the feed portion, and a member normally closing the tubular member and designed to be moved to close the feed opening.

4. In a device of the character described, the combination of a body havin a reservoir formed therein and comprising a eed portion provided with a chamber, a dipping well bemg formed at the bottom of the chamber and "a feed opening being provided which com-' being provided w ich municates between the reservoir and the dip ing well, a tubular member extending witliin the chamber, and a spring arm located within the chamber and normally closing the tubular member, the said spring arm being adapted to also close the feed opening.

5. In an ink well, the combination of a body portion provided with a reservoir and a dipping well, a feed opening being formed in the body portion and establishing communication between the reservoir and the dipping well, and a spring arm arranged within the dip ing well and normally closing the inlet to t e dipping well, the said spring arm being adapted to be deflected to close the before mentioned feed opening.

In testimony whereof I aliix my signature in presence of two witnesses.
